December 2007 approved par (Project Authorization Request) to develop the next generation Network 40g/100g Ethernet standards. The next-generation standard IEEE 802.3BA will be introduced in June 2010, according to the plan. 40G and 100G at present, the future of the application is mainly concentrated in the data, when the server a wide range of 10gbase-t, the speed of core exchange must be followed by a significant increase.

This article is from DBAnotes. Original article title: DRBD and Pacemaker If someone asks you if a PC server can reach 99.99% high availability, what should you do? Maybe no machine can "Make sure" to achieve this availability. Of course, there may be no problems in a certain period of time, but it must be luck, however, high availability is basically impossible to achieve the goal through one machine. More often, we design solutions to ensure that the faulty machine is taken over as soon as po

update pages in shared storage, which is effective for all servers. The Distributed File System provides good scalability and availability. When the storage space of the Distributed File System increases, the storage space of all servers also increases. For most Internet services, they are Read-intensive (Read-intensive) applications. Distributed File systems use local hard disks as Cache (such as 2 gbytes space) on each server ), the local access speed to the distributed file system is close t

(scale out) To scale horizontally (or scale out) means to add more nodes to a system, such as adding a new computer to a distributed software application. an example might be scaling out from one web server system to three. As computer prices drop and performance continues to increase, low cost "commodity" systems can be used for high performance computing applications such as seismic analysis and biotechnology workloads that cocould in the past only be handled by supercomputers. hundreds of sm

performance of the next-generation Pascal architecture, it has to say nvlink, which speeds data transfer between the GPU and GPU, between the GPU and the CPU, 5 to 12 times times faster than the existing pci-express standard, and for deep learning these applications that require higher GPU transfer speeds is a great boon. Developers should be pleased that Nvlink is based on point-to-point transmission, with the same programming pattern as pci-express.Nvidia says that Nvlink can increase the num
